How Many Solar Panels Would It Take to Power The Entire World? [Data]

In this article, they discuss covering an area the size of Spain with solar panels. Mostly placing them in deserts. I wonder if we could reduce the greenhouse effect by absorbing normally reflected energy into these large panels in the desert. This article also only deals with our current power demand. What happens when we start in with the electric cars? Will there be such a paradigm shift that we will have to start creating more CO2 again to keep the planet warm?

How Many Solar Panels Would It Take to Power The Entire World? [Data]

Just 496,905 square kilometers. That's really nothing compared to the total world area: Less than the surface of Spain (504,030 square kilometers) covered with solar panels, distributed across deserts and areas with almost 24/7 sun, all year around.
